Question

Which command is used to display the name of the operating system?

• A. OS
• B. Unix
• C. Kernel
• D. Uname

Hint:

Use the{uname} command in Unix-based systems to get important system information, including the operating system's name.

Answer 1

The Correct Option is D

The correct answer is Uname.
Theuname command is used in Unix-based operating systems (such as Linux and macOS) to display information about the system, including the name of the operating system, the machine's architecture, and other system details. When used with the-s option (i.e.,uname -s), it will display the operating system name.
Explanation of Other Options:
(A) OS:
There is no command calledOS to display the operating system's name.OS is just a general term used for the operating system.
(B) Unix:
Unix refers to a family of operating systems, not a command. You cannot useUnix to display the system's name.
(C) Kernel:
The kernel is the core part of an operating system but is not a command that can be used to display the operating system's name. The kernel handles low-level system operations, such as process management and hardware interaction.
Summary:
- The correct command to display the name of the operating system isuname.

-OS,Unix, andKernel are not valid commands for displaying the operating system's name.
